Yeah. I did. As I said, what seems to happen is the teeth push the piston upward a bit and it seems to get jammed against the top of the gearbox shell.
Like I said it all works perfectly smooth with the gearbox shells apart, only does this once I put it back together..

I don't think so. The piston has shorter teeth but it's not a half tooth. That picture above isn't a very good angle but the strip of steel that goes alongside the teeth is actually even with the crest of the piston teeth, not the root. The sector gear rotates freely through the half rotation where the teeth don't touch the piston and I did make sure I had it shimmed so that the teeth lined up properly left to right.
